During an assessment of the cranial nerves, the nurse finds the following: Asymmetry when the client frowns, uneven lifting of the eyebrows, sagging of the lower eyelids, and an escape of air from the right side when the client puffs their cheeks. This would indicate the dysfunction of which of the cranial nerves?
Motor component of IV (Trochlear)
Motor and sensory components of XI (Accessory)
Motor component of VII (Facial)
Motor component of X (Vagus) and sensory component of XII (Hypoglossal)
The Correct Answer is C
A) Motor component of IV (Trochlear): The trochlear nerve primarily controls the superior oblique muscle of the eye, which is responsible for downward and lateral eye movements. The findings described do not relate to eye movement and therefore do not indicate dysfunction of this nerve.
B) Motor and sensory components of XI (Accessory): The accessory nerve innervates the sternocleidomastoid and trapezius muscles, primarily affecting head rotation and shoulder elevation. The symptoms noted in the assessment do not pertain to these muscle functions, so this option is not correct.
C) Motor component of VII (Facial): The signs of asymmetry in frowning, uneven eyebrow lifting, sagging eyelids, and air escaping when puffing the cheeks are characteristic of dysfunction in the facial nerve (cranial nerve VII). This nerve controls the muscles of facial expression, and impairment would lead to the described asymmetrical movements.
D) Motor component of X (Vagus) and sensory component of XII (Hypoglossal): The vagus nerve affects autonomic functions and some swallowing muscles, while the hypoglossal nerve controls tongue movements. Neither nerve is primarily responsible for the facial expressions described in the assessment findings, making this option incorrect.

Correct Answer is C
Explanation
A) Obtain an order for a catheter: While catheterization can help manage elimination needs, it is generally considered a more invasive approach and is not the first line of action unless absolutely necessary. The goal should be to maintain the client’s dignity and encourage as much independence as safely possible.
B) Allow the client to walk independently: Given that the Romberg test is positive, indicating potential balance issues, allowing the client to walk independently could increase the risk of falls and injury. Safety is a primary concern in this situation.
C) Obtain a bedside commode: This intervention is appropriate as it provides a safe and accessible option for the client to meet their elimination needs without the need to navigate to a bathroom, which may be challenging given their balance issues. A bedside commode allows for easier access while minimizing the risk of falls.
D) Limit fluid intake: Limiting fluid intake is not a safe or effective way to address elimination needs and could lead to dehydration and other complications. Encouraging appropriate fluid intake is important for overall health, provided the client can manage elimination safely.
Correct Answer is D
Explanation
A) The patient has asthma: While asthma can lead to respiratory symptoms and issues, it is not typically associated with clubbing of the fingernails. Asthma primarily affects airway constriction and inflammation, rather than causing the long-term changes in nail morphology seen with clubbing.
B) The patient has cardiovascular disease: Although some cardiovascular conditions can lead to clubbing, it is more commonly associated with chronic lung diseases. Cardiovascular disease might cause other signs or symptoms, but clubbing alone is not a definitive indicator of this condition.
C) The patient has emphysema: Emphysema, a type of chronic obstructive pulmonary disease (COPD), is characterized by the destruction of lung tissue and impaired airflow. While it can contribute to hypoxemia, clubbing is not a common finding specifically associated with emphysema.
D) The patient has chronic hypoxemia: Clubbing of the fingernails is a classic sign of chronic hypoxemia, often resulting from long-term respiratory conditions like COPD, interstitial lung disease, or lung cancer. It indicates a prolonged lack of oxygen in the blood, leading to changes in the nail bed and digit shape. Given the patient's long smoking history, chronic hypoxemia is the most likely explanation for this finding.
